Prison of the Damned (pt. 2)

There's a Cerberus attacking you, so kill it off. Now, use the Amulet to heal what's in front of you later stay to your right. You'll see stairs close to the wall. Step into and move forward. At the end, you'll see a Gorgon's Eye chest. Continue forward and go to the left for a Phoenix Feather and red orb chest.

Turn around and go to the right to find a door to enter. Watch the cutscene. After, turn around for multiple chests and if you go back to the door, you can find the Orkos' Cloak.

Orkos' Cloak can be found in the Prison of the Damned (pt. 2) right after a long cutscene where Kratos kicks what looks like the Spartan King off a cliff.

Now go to the left, and get sealed in. What is this, Zelda? Kill off the monster, then it's time to channel our inner Ezio. Climb up onto the bit jutting out of the pillars. Move all the way to the right of the building, then jump up to the second floor. Keep climbing up the building until you get to the top.

Kill the enemies here, then jump down and kill the new enemies down here. Use the Amulet to heal the buildings in front of you, then jump down to get to that green grapple point. Time to swing! Jump along the green grapple points until you make it back up to the top of the structure.

Go down the stairs and to the right. There's a red orb chest that you can revive then immediately smash.
